Heat-preservation, heat-insulation and noise-reduction stone-like paint and preparation method thereof

Technical Field

The invention relates to a heat-preservation, heat-insulation and noise-reduction stone-like paint and a preparation method thereof, belonging to the technical field of paints.

Background

In China, the energy consumption of buildings (the energy consumption of buildings in the whole production and use process) and the energy consumption of the production of maintenance structural materials account for about 30 percent of the total energy consumption of the whole country. Along with the advance of urban construction in China, the proportion of building energy consumption in the total energy consumption is continuously increased, and building energy conservation (which means that the energy utilization efficiency in a building is improved and the building energy consumption is reduced on the premise of not reducing the using function of the building) becomes a primary task of improving the social energy using efficiency. The heat-insulating and heat-preserving coating in the building energy-saving material is more and more favored by people due to the advantages of economy, convenient use, environmental protection, good energy-saving effect and the like, and has bright development prospect.

The paint which is coated on the surface of a building and can play a role in heat insulation is called as building heat insulation paint. The architectural heat insulating coating is classified into barrier type heat insulating coating, reflective type heat insulating coating and radiant type heat insulating coating 3 according to the difference of heat insulating mechanism and heat insulating manner. The 3 types of coatings have different heat insulation mechanisms, different application occasions and different effects, and can be said to be different in different seasons.

The stone-like paint has decorative effect similar to that of marble and granite. It is mainly made up by using natural stone powder with various colours, and can be used for imitating stone effect of external wall of building, so that it is also called liquid stone. The building decorated by the stone paint has natural and real natural color, gives people elegant, harmonious and solemn aesthetic feeling, and is suitable for indoor and outdoor decoration of various buildings. Especially, the decoration on the curved surface building is vivid and lifelike, and has an effect of returning to nature. Along with the increasing requirements of people on living environment in recent years, the usage amount of the real stone paint is also increased year by year.

At present, although many research reports and research on heat insulation coatings are carried out, and a large number of documents and application situations are reported, most of building heat insulation coatings are flat-coated, and sand textured coatings such as stone paint texture paint and the like for heat preservation and heat insulation are rarely mentioned. At present, stone-like paint with heat insulation and heat preservation effects is urgently needed in the market to meet the use needs of people.

The inventor group obtains a real stone paint which is water-based, environment-friendly, good in construction performance, good in construction effect, heat-insulating and noise-reducing and fills the market blank by continuously screening raw materials, reasonably matching special functional auxiliaries and selecting a special process with technical support in the existing coating industry.
